I'll be honest. I only have a vague idea of what's going on in this anime. There's a magical force called "Aho", weapons are powered by "Brain Crystals", and there are boobs...sorry, got distracted. Onto the synopsis!

Photon is a simple child. He does what's he's told, protects his friends, and is polite to everyone he meets. He's also superhumanly strong and damn near indestructible. He spends a good deal of his time chasing down his foolish "sister" Aun who is always running off after whatever man she's in love with this week.

One of these chases leads Photon through some ruins sitting on top of a recently crashed spaceship. Through a humorous cultural misunderstanding, he finds himself married to the sole occupant of that ship: a beautiful, nubile woman named Keyne. Photon has no idea what's going on, but he decides this woman is his friend and that she deserves protection. She quickly needs this protection when forces following her discover the link between Keyne, Photon, and the powerful energy force "Aho".

That roughly describes the first five of the six episodes of the series. These episodes are pretty funny throughout whether the jokes are coming from Aun and Keyne fighting over Photon, the antagonist Papacharino showing up with a weapon powered by EVEN MORE brain cells than last time, or just Photon having no clue what is going on around him. There's a great scene where Aun walks into a pharmacy constructed by Papacharino seconds before, buys pills to poison Keyne, and leaves, not noticing the building being dismantled immediately after she leaves. I'm skipping over a lot of the funny scenes (check out the stills for a few previews), but, trust me, there are plenty more. The humors relatively simple most of the time, but it'll keep you entertained.

The sixth episode is another beast entirely (at least for five or ten minutes in the middle). A character suddenly becomes truly and surprisingly villainous and initiates one of the better fight scenes I've seen. While I liked the rest of the series, the score would be several points higher if the creators had maintained that level of quality throughout the series.

My main complaint is that the plot was a little hard to follow aside from the shallow, superficial plots. There's some sort of energy called Aho that runs a lot of stuff in the universe but only exists because of an "engine" that was built a few decades back (apparently Aho was adopted very, very quickly as the universal energy source). No one really knows where the engine is located since its creator was horrified that Aho was being used to power weapons (where Aho is apparently focused by "Brain Crystals", which are never really explained). There's a key to the engine, there's "un-Aho", and there's a bunch of other stuff that is likewise only briefly touched on while Photon walks around clueless. I really wish these plot points had been discussed more as I usually find that the best part of science fiction is the pseudo-science.

Overall, it was good. It was a light-hearted sci-fi tale with a decent amount of boob shots. The sixth episode almost pulls the series up a half-point, but I think "Photon: the Idiot Adventures" is stuck at a 7/10.
